The field experiment was conducted at Student’s Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, (UP) during Rabi season December 2021-April 2022. In the field environment, the growth of wheat was greatly influenced by temperature changes associated with sowing dates. The field experiment laid out in split plot design (SPD) with 4 replication and 3 different date of sowing (30^th Nov, 15 Dec and 30 Dec) in main plot against 4 varieties of wheat crop (HD-2733, K-307, K-9107 and HD-2967) in sub plot. Growth parameters were higher in early sown crops as compared with late sown wheat crops. Among varieties HD-2967 sown on 30th Nov obtain highest growth parameters as compare to HD-2733, K-9107 and K-307. It may be concluded that optimum sowing time of wheat crop is 30th Nov as compare to late sown wheat. Among the most promising variety.

The sowing on 30th November recorded better growth, yield attributes and grain yield (44.94 q ha^-1) and harvest index (39.05%) of wheat crop. Among wheat varieties tested HD-2967 exhibited maximum grain yield (42.30 q ha^-1) and harvest index (39.34%) compared to other varieties.
